WoW you have a job that pays you to be here with us, that's awesome!

My current job really does need me to stay so late and I'm the only one there with grade school children. When I was first hired I worked all evening hours and now that I've been there six years feel there is no reason for them not to let me work 9-4 during the school year. The last hour or two of work there is nothing for me to do.
